I've Googled this, but come up blank, so it's down to you lot ;-)
Why on earth don't they play the original songs for the dancers to dance to? I've just heard the singers murder Debarge's Rhythm of the Night, admittedly the original wasn't that great to start with, but this was dire!
I dont usually pay that much attention to the programme never mind the songs. I have obviously noticed they're always performed by singers, and are usually just ok, sometimes bad- its just this one was that bad I noticed immediately.
